12. You are saving money each year to send your child to college. You plan to put $5000 away each year for the next 12 years, until the child is ready to start at SUNY Potsdam.

13. You are considering investing in an apartment building and need to calculate the NPV of the associated cashflow. The building will cost $450,000 to purchase and you expect to own it for 20 years.You will finance this with a bank loan at a 5% effective interest rate. You expect to see the following cashflow and should use this in calculating the NPV of the deal.

• Rental revenue = $61,000 per year
• The apartments must be repainted and serviced every 5 years at a cost of $17,000 for each painting/servicing. This is $17,000 in years 5, 10, and 15. You will not repaint in year 20.
• At the end of 20 years, you expect to hire an arsonist to burn the property to the ground. The arsonist will cost you $25,000 and the insurance company will pay you $250,000 for the destroyed building and land. Assume that you will get away with this fiendish plan and ignore the legal risks.

What is the NPV of this cashflow?
